The Schmidt-Cassegrain Telescope demonstrated in this tutorial is a classic design using an aspheric corrector lens and two spherical mirrors. The aspheric corrector is created using the 'Aspheric Even Lens 3D' part from the Ray Optics part library. Mehr lesen
Dieses Modell verwendet das Wave Optics Module und das Ray Optics Module, um die Ausbreitung von Strahlen durch ein Beugungsgitter bei verschiedenen Einfallswinkeln zu modellieren. Es verwendet die S-Parameter, die mit dem Interface Electromagnetic Waves, Frequency Domain auf einer ... Mehr lesen
A paraboloidal dish can concentrate solar energy onto a target (receiver), resulting in very high local heat fluxes. This can be used to generate steam, which can be used to power a generator, or hydrogen, which can be used directly as a fuel source. In this model, the heat flux arriving ... Mehr lesen
Compact camera modules are widely used in electronic devices such as mobile phones and tablet computers. In order to reduce both the size and number of elements required the optical design will typically incorporate several highly aspheric surfaces. This model demonstrates a five element ... Mehr lesen
A modern high-power industrial fiber laser system can deliver up to 3kW of single-mode laser radiation on to surfaces to be cut, drilled, welded or marked. Even using highly transmissive materials, the optical component used to focus the laser beam onto target surfaces can be affected ... Mehr lesen
Anti-reflective coatings are frequently used in optical systems to reduce the amount of stray light produced when a beam of light crosses from one medium into another medium with a different refractive index. The simplest example of an anti-reflective coating is a quarter-wavelength ... Mehr lesen
This tutorial shows how to set up a multi-element objective lens. The chosen lens is a Petzval lens with field flattener described in 'Fundamental Optical Design', by M. Kidger, 2001, pg 192. The tutorial demonstrates how to include a geometric sequence using the 'Spherical General Lens ... Mehr lesen
This example demonstrates how to import a bitmap which can be used to simulate an image using ray tracing. The example is based on the Double Gauss Lens tutorial from the Ray Optics Module Application Library. The first study has been modified so that the Spot Diagram "auto-focus" tool ... Mehr lesen
This example shows how to perform parameter optimization on a lens system. The optimization is motivated by the replacement of one of the glasses in a prior optical prescription with a new glass having slightly different optical dispersion coefficients. The control parameters are the ... Mehr lesen
A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies, with minimal losses. In this tutorial a Bragg reflector is modeled with a central wavelength of 550[nm] ... Mehr lesen
